Figure 23 BC and Continuous Access XP Journal: Shared P-VOL/P-VOL and P-VOL/S-VOL
.
The configuration shown in Figure 24 is an example of a volume that functions as both a BC S-VOL
and a Continuous Access XP Journal P-VOL. This configuration allows you to use Continuous Access
XP Journal to provide remote copies of BC S-VOLs.
Figure 24 BC and Continuous Access XP Journal: Shared S-VOL/P-VOL
.
NOTE:
In the configuration shown in Figure 24 , you cannot perform the Business Copy XP and Continuous
Access XP Journal copy operations at the same time. In Figure 24 , first you need to create and split
the Business Copy XP pair, then create the Continuous Access XP Journal pair. If you want to
resynchronize the Business Copy XP pair, suspend the Continuous Access XP Journal pair beforehand.
Note that you cannot change the Continuous Access XP Journal pair status while the Business Copy
XP pair is in PSUS(SP) status.
NOTE:
Usually Continuous Access XP and Continuous Access XP Journal can share volumes with BC. However,
in some cases, you cannot create BC pairs using volumes shared with Continuous Access XP and
Continuous Access XP Journal. For more information about combining BC, Continuous Access XP,
and Continuous Access XP Journal, see
Figure 19 and Figure 20 .
